For realizing adopting under the different condition the suitable brill mode of sending, electric-controlled hydraulic dish stop (10) is housed on drum shaft (4).Small machine automatic driller (8) connects drive roller shaft (4) by power-transfer clutch (9) and through gear reduction box (3), coupler (7) simultaneously.The sending auger spindle and small machine drill feeding facility (8), send and bore power-transfer clutch (9) and connect of gear reduction box (3), small machine drill feeding facility (8) is one or two on winch, and is installed on any spindle nose of gear reduction box (3).
The utility model adopts the power-transfer clutch of different structure, and its power-transfer clutch installation site and mode are slightly different.Below be the frame mode of friction clutch and gear clutch:
Described power-transfer clutch is friction clutch (5,6), and described power-transfer clutch (5) and power-transfer clutch (6) be installed in gear reduction box (3) input shaft end and middle axle head respectively, perhaps is installed in the input shaft two ends or the tween drive shaft two ends of gear reduction box (3).
Described power-transfer clutch is tooth clutch (11), and this tooth clutch (11) is installed between gear reduction box (3) input shaft two gear Z1 and the Z3 or between tween drive shaft two gear Z2 and the Z4.
Hoist gears drop-gear box (3) is one or two; Electrical motor (1) is one to four simultaneously.
The utility model structurally not only drop-gear box be gear reduction box, winch has two gears, unsnaps or hangs by two (during drop-gear boxs) or four (during two drop-gear boxs) power-transfer clutchs and close (or left and right the extension respectively of tooth-like shift clutch closed) and implement gearshift; And the automatic bit feed of winch send brill with AC frequency conversion master motor (1) under normal conditions, under ulf with the electric-controlled hydraulic dish stop (10) send and bore or adopt small machine drill feeding facility (8) to send brill.Therefore, the utility model compared with prior art, winch motor can adopt revolution ratio now to get final product with the lower alternating-current variable frequency motor of motor (being that range of motor speeds is at 0-2000r/min), (maximum speed of revolution reaches 2800r/min need not adopt special wideband hyper-speed motor, work is relatively more dangerous), drop-gear box precision and manufacturing difficulty can suitably reduce, and have solved the height of winch accuracy requirement in the past, make difficulty, problems such as the winch hoisting speed is slow, inefficiency.The utility model winch has the reliability height, and safety is good, and range of speed was big after winch adopted two retaining structures, high efficiency.
